Andre Guedes b697646b11 x86: Cleanup Makefile.x86_common
This patch does several cleanups in Makefile.x86_common file. The
changes are described above.

1) The CFLAGNO variable was removed since it is used only to assign
   the CFLAGS variable. Also, CFLAGNO is not used outside Makefile.x86_
   common.

2) The "-I/usr/local/include" option was removed since we provide manually
   the include path from newlib in the bsp/ directory.

3) We only support building x86-based platforms on Linux so there is no
   point in setting LDFLAGS conditionally.

4) The '-export-dynamic' option was removed from LDFLAGS since we are not
    creating a dynamically linked executable.

5) Makefile.x86_quarkX1000 is the only one that includes Makefile.x86_
   common. Since it doesn't use the custom rules from Makefile.x86_
   common we remove them.

Andre Guedes 13bbe8a5b5 x86: Don't generate .note.gnu.build-id section
This patch adds "--build-id=none" to default LDFLAGS so
.note.gnu.build-id section is not generated. This section
contains unique identification for the built files what is
not important to us (at least at this moment).

This change simplifies all linker scripts for SoCs based on x86
(at this moment we only have Quark X1000) since we don't have to
care about it anymore.

Jesus Sanchez-Palencia e4bc1a1e8c x86: Add init folder and move code accordingly
The x86/init/common/ folder holds all cpu initialization
code - idt and gdt setup, interrupts and cpu initialization.

On this folder will also sit any SoC specific implementation of
the functions called from cpu_init().

Jesus Sanchez-Palencia b2fa72bb98 x86: Break Makefile.x86 into common and pc specific ones
Now the cpu/x86/ provides a Makefile.x86_common and a
Makefile.x86_pc. The former includes the common Makefile
and adds legacy pc specific implementations (currently,
drivers only) into the building context, while the latter
has everything that defines the bootstrap of a x86 CPU.

This commit also fixes platform/galileo/ so it includes the
correct makefile - Makefile.x86_quarkX1000. Galileo uses
a Quark X1000 SoC which is not an IBM Generic PC-like CPU,
but it does provide most of a PCs peripherals through
its "Legacy Bridge". Thus, it makes sense that QuarkX1000's
Makefile includes code from the legacy_pc x86 cpu.
